Hey HN!

Last week I was working on a website and needed a way to synchronise visuals with live music.

I've used MIDI controllers for this before, but I am travelling right now and don't have mine with me. So I had the crazy idea to build a browser extension that uses the keyboard as input and includes a sequencer. I gave myself 24 to work on it.

It ended up taking longer (of course), specially since I ended up creating a demo, a small landing, docs, and an intro video. Took me one week from idea to launch (pushed quite a bit tbh).

Features:

- Works as a browser extension. Atm distributed through chrome web store only.

– 8 customisable channels. Each channel has 3 modes: sequencer, keystroke and random.

- It sends post messages to the current page. Use however you want.

- Works with your keyboard. The key bindings are designed for expressive live usage.

- Advanced tempo controls. Easy to synchronise with live music using the ‘tap temp’ feature.

- Open Source, all code in github.

Anyway, let me know what you think.
